Ubuntu Security Notice USN-6923-2
July 30, 2024<\/p>\n
linux-aws-5.15, linux-ibm, linux-ibm-5.15, linux-raspi vulnerabilities
==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 22.04 LTS
– Ubuntu 20.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
– linux-ibm: Linux kernel for IBM cloud systems
– linux-raspi: Linux kernel for Raspberry Pi systems
– linux-aws-5.15: Linux kernel for Amazon Web Services (AWS) systems
– linux-ibm-5.15: Linux kernel for IBM cloud systems<\/p>\n
Details:<\/p>\n
Benedict Schl\u00fcter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde
discovered that an untrusted hypervisor could inject malicious #VC
interrupts and compromise the security guarantees of AMD SEV-SNP. This flaw
is known as WeSee. A local attacker in control of the hypervisor could use
this to expose sensitive information or possibly execute arbitrary code in
the trusted execution environment. (CVE-2024-25742)<\/p>\n
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
– TTY drivers;
– SMB network file system;
– Netfilter;
– Bluetooth subsystem;
(CVE-2024-26886, CVE-2023-52752, CVE-2024-36016, CVE-2024-26952,
CVE-2024-27017)<\/p>\n
Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
package versions:<\/p>\n
Ubuntu 22.04 LTS
linux-image-5.15.0-1059-ibm 5.15.0-1059.62
linux-image-5.15.0-1059-raspi 5.15.0-1059.62
linux-image-ibm 5.15.0.1059.55
linux-image-raspi 5.15.0.1059.57
linux-image-raspi-nolpae 5.15.0.1059.57<\/p>\n
Ubuntu 20.04 LTS
linux-image-5.15.0-1059-ibm 5.15.0-1059.62~20.04.1
linux-image-5.15.0-1066-aws 5.15.0-1066.72~20.04.1
linux-image-aws 5.15.0.1066.72~20.04.1
linux-image-ibm 5.15.0.1059.62~20.04.1<\/p>\n
After a standard system update you need to reboot your computer to make
all the necessary changes.<\/p>\n
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.<\/p>\n
